FUEL-BRIQUET AND PROCESS OF MAKING- SAME.

To all whom it may concern:

Be it known that we, MAX SALOMON and GEORGE SALOMON, citizens of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented new and useful Improvements in F u'el-Briquets and Processes of Making Same, of which the following is a specification.

This invention has reference to improvements in fuel briquets and more especially in briquets wherein powdered coal dust is employed as the base. It comprehends primarily the production of a briquet composed of coal dust, resinous matter, and a suitable binder, the component mass, after having been molded, possessing a high coeflicient of heat and retaining its form without danger of crumbling or disinte ration during handling and during its initia stages of combustion.

The improved briquet is constructed in the following manner and from thev followin ingredients :One ton of coal dust is dried and thoroughly heated after which 50 lbs. of powdered resin are sprinkled over the dust and mixed thoroughly therewith. Over the mass thus formed 3 gallons of lue, preferably of the brand known as crystal cement are poured in a slightly diluted state over the mass of dust and resin and the three elements then thoroughly mixed, the coal dust being kept at a temperature of about 40 during the mixing operation. The final mass is then placed in suitable molds and compressed in the ordinarymanner.

'The resin employed renders the briquet capable of ready ignition while the glue serves to cohere the particles of dust and resinas will be apparent.

Crystal cement consists of one pound Specification'of Letters latent.

Application filed April 13, 1910. Serial No. 556,389.

Patented Jilly 26, 1910.

of Ordinary carpenters glue to which is purpose of ignition but also cohesion, inasmuch as the cement will not act as a binder withoutthe resin. 7

What is claimed is:

1. A process of producing a fuel briquet which consists in heating and drying coal dust, mixing powdered resin with the coal dust and finally in pouring liquid glue over the mass and again mixing the same in the presence of heat.

2. A fuel briquet composed of coal dust, powdered resin, and a binder formed of glue and Portland cement, the binder being heated to the boiling point and being poured over the mixture of coal dust and resin while heated, the resin coacting with the cement to complete the binder.

In testimony whereof we have hereunto set our hands in presence of the subscribin--' witnesses.
